Maryland flying changes quickly from Baltimore-area towered fields to quiet non-towered airports on the Eastern Shore and in the western hills. KBWI (Baltimore/Washington Intl Thurgood Marshall) is the state’s big runway airport, with 10,503 ft available, three runways, ILS capability and an FBO. It is the right tool when runway length and full-service infrastructure drive the plan. For general aviation, the more practical daily choices often sit outside KBWI. KFDK (Frederick Muni) gives pilots a towered field, ILS, 5,819 ft runway and an FBO. KMTN (Martin State) provides a 6,999 ft runway at 22 ft elevation near Baltimore. KHGR (Hagerstown Rgnl/Richard A Henson Fld) adds a 7,000 ft runway, tower service and an ILS in western Maryland. The state also has strong non-towered options. KOXB (Ocean City Muni) is a coastal field with an ILS, 4,074 ft runway and 16 ft elevation. 2G4 (Garrett County) is the performance-planning outlier, with a 5,000 ft runway at 2,933 ft elevation. Maryland is not a large state, but pilots still need to brief airspace, runway length, moisture, terrain and fuel availability with care.
